AN RNA-BASED CLINICAL DIAGNOSTIC ASSAY USED TO IDENTIFY ACTIVE MICROBIAL INFECTIONS
Studies reveal the clinical efficacy of the CSI-Dx assay.

APPLIED RESEARCH

Studies reveal the efficacy of the CSI-Dx technology in a variety of clinical applications.

The human microbiome has been linked to the development of several malignancies, but there is scarcity of data on the microbiome of bladder cancer patients. In this study, we analyzed microbial composition and diversity among patients with and without bladder cancer. Samples were collected from 38 urothelial carcinoma (UC) patients and 10 noncancer controls from August 2018 to May 2019.

There is incomplete knowledge of the impact of bone marrow cells on the gut microbiome and gut barrier function. We postulated that diabetes mellitus and systemic ACE2 (angiotensin-converting enzyme 2) deficiency would synergize to adversely impact both the microbiome and gut barrier function. Bacterial 16S rRNA sequencing and metatranscriptomic analysis were performed on fecal samples from wild-type, ACE2-/y, Akita (type 1 diabetes mellitus), and ACE2-/y-Akita mice.

It is unclear whether the favorable effects of walnuts on the gut microbiota are attributable to the fatty acids, including α-linolenic acid (ALA), and/or the bioactive compounds and fiber. This study examined between-diet gut bacterial differences in individuals at increased cardiovascular risk following diets that replace SFAs with walnuts or vegetable oils. Forty-two adults at cardiovascular risk were included in a randomized, crossover, controlled-feeding trial that provided a 2-wk standard Western diet (SWD) run-in and three 6-wk isocaloric study diets: a diet containing whole walnuts (WD; 57-99 g/d walnuts; 2.7% ALA), a fatty acid-matched diet devoid of walnuts (walnut fatty acid-matched diet; WFMD; 2.6% ALA), and a diet replacing ALA with oleic acid without walnuts (oleic acid replaces ALA diet; ORAD; 0.4% ALA).

This study sought to characterize the bacterial and fungal microbiota changes associated with Clostridium difficile infection (CDI) among inpatients with diarrhea, in order to further explain the pathogenesis of this infection as well as to potentially guide new CDI therapies. Twenty-four inpatients with diarrhea were enrolled, 12 of whom had CDI. Each patient underwent stool testing for CDI prior to being treated with difficile-directed antibiotics, when appropriate.
